Helium @ Large Hadron Collider - Periodic Table of Videos

[Inviting1word]

i like the dramatic zoom after he says magnets

[heasby]

I want to touch his hair. Like, a lot.

[sagarcooldirector]

am i lucky to understand english? :)

[Vennificus]

Taking your tea to the top of a mountain is a bad Idea, just because the water is boiling doesn't mean it's hot

[IP115]

hey crazy

[BlockisticStudios]

@IP115

you stupid

[husseler]

4 degrees Kelvin? Isnt it just 4 Kelvin?

[diogenden]

u r such an idiot. Einstein is the right name.

[conoba]

Are you trying to speak english?

[pdubs926]

yes and r u trying to be a jeark maby i have problems speelling

[DeltaPhi79]

And with grammar. (* will denote corrections) *jerk, *maybe, *spelling. Between jerk and maybe: PERIOD. Now I don't mean to really offend you, but you really shouldn't try to speak a language if you either don't know the grammar or spelling.

[limefrog77]

@DeltaPhi79 what arrogant drivel that is....it suits your screen name

[limefrog77]

@pdubs926 he obviously IS a jerk. His screen name just screams snotty frat man

[BinaryReader]

this dudes hair is unreal :D great vid

[Rakyth]

I feel like I'm listening in on a college course lecture for free XD

[DanceDanceJoe]

this guy is like the non-german einstein

[spike0804]

no...he was definitely German born....

[porsche911sbs]

to be picky, this guy's a chemist, Einstein was a physicist.

[wtfisthis1990]

awesome hair :D

[cmvelaz]

Correct, thanks periodicvideos!

[cmvelaz]

Where are the spanish subtitles, I don't understand anything!

[periodicvideos]

Did you try switching the subtitles on with the little arrow at the bottom right of the video - they are working for me!

[ElveeKaye]

Thanks for explaining this in a way that's easy to understand. I'm learning more from these videos than I did in high school science classes!

[bamafb77563]

no idea what hes talking about

[calvinhobbesliker]

the reaction at the end was a gram of potassium with water

[TheOnlineCommunity]

Stereotypical scientist if ever I saw one...

[xmrwaffles2]

hes just highly educated so much in fact he even grew the little fro to accumulate the size of his brain

[LordVith]

I think you mean accommodate.

[spathieluder]

He probably needs the fro to quickly dissipate the heat being emitted from his cranium due to increased brain activity. Very much like a heat sink on a computer processor.

[JacobRudduck]

Best comment i've ever seen on this channel

[argosftw]

one of the best ive seen in a while lol

[Ogaitnas900]

But wouldnt it trap air inside it, making it move very little, slowing down convection? Like a scarf :P

[gedasltu]

Why the boiling temperature of liquid hydrogen is higher than liquid helium? Molecules of hydrogen are smaller than helium atoms so the interaction between particles in liquid hydrogen are weaker. According to this, the boiling point of liquid hydrogen should be lower than helium... Or I just don't get it? Please, explain.

P.S. sorry for my english if it is not correct.

[billy210uk]

im guessing its cos at the end of the day a molecule of hydrogen contains two atoms as opposed to helium which has just the one (Mrs Wembley).

[dracarys666]

it is mostly due to the interactive forces between the molecules.

Hydrogen's intermolecular forces are very weak, but they do exist, allowing hydrogen to condense to a liquid.

Helium has almost no intermolecular forces, which explains its tendency to form superliquids and its resistance to forming a solid even close to absolute zero temperatures.

hope that helps

[gedasltu]

Thank you very much, it's very interesting (all that cryogenic things). Where can I read about it (do you know some web-pages)? Wikipedia is not enough for me :) I have one more question: How these interaction forces between liquid hydrogen and liquid helium molecules appear? Van Der Waal's forces or what?

[garethb1961]

gedasltu,

hydrogen molecules are bigger than helium atoms - longer certainly along the inter-atomic axis. Also, the 2 electrons are more weakly bound than those of helium - meaning they are freer to form instantaneous dipole moments, thus increasing their strength of interaction.

Size is over-rated. Number of electrons is a more significant parameter in these weak binding forces. H2 and He both have 2 electrons, but the H2 ones are more loosely bound.

[TzekeT]

anyone else get distracted by the fact hes linked two computer screens together?..in the back lol

[AmrasAco]

i was lol

[SatanicMonkeyLord]

what's special about that?

[MCBSOAD]

Just that you can drag and drop/ use programmes with two screens asif they where just one.. pretty cool... radios use them quite alot

[iloveonew]

i noticed it, lol..

i was like, eh? the two screens linked each other? xD

[ONarmoO]

i noticed it too! And for a few minutes I've been just watching it....

[Promitheas85]

ffssst round the corner

[briandbz23]

BRains and an ill Fro, thats all you need. this guy is the man

[halfbreed02]

Why do smart people look like that? :)

[AmrasAco]

I suppose they might make similar facial expressions throughout their career while thinking about "science stuff." Effectively shaping their faces (and ect.) as such.

Or to put it bluntly:

"They make nerd faces and get wrinkles, lol"

[MercurialHeist]

Interesting theory,but explain the hair

Such rhetorical coiffure cannot be mere coincidence surely?

[MercurialHeist]

* oh,that wasn't typed in a trolling tone

Your comment made me lol

[prozrachno]

Reality is amazing stuff! :]

[Co0Ps]

Science!

[shaurz]

Helium is liquid at absolute zero. To make it solid you have to put it under high pressure forcing the atoms closer together.

[drumbum99]

everything is solid at absolute zero. Well kind of, absolutly everything stops moving at all. It has no energy (other then its mass), so pretty much 0K is theoretical and not practical at all.

[arnolddisco]

You guys should use Firefox

[Vierkirschbaum]

I love your way of explaining.

I'm not a native speaker, but it was very comprehensible.

[theartfuldoger]

i really like the hairstyle

[j5972]

this is what happens when you hook a womble to a plug socket.

[ish391]

loooool r u serios

[Tangointheface]

when are they starting it again?

[add1c7i0n]

mid 2009 i believe

[Dries90]

They first have to warm those sectors up to room temperature to be able to repair them. Then comes the obligatory maintenance period, so they'll restart the LHC probably early spring 2009.

[daflamer]

great

[babebraman]

this guy is my hero!! keep it up guys!! awesome!!

[Hannahcubed]

I thought the video was very informative and well done! Btw, commenting on the narrator's hair is not an appropriate response to a science video like this one.

[Kardemian]

lol hair

[limlynn999]

What about oil???

[wizeguy]

errmm i didnt get a single thing he was on about, thats probably why im not a scientist, ohh well with hair like that i dont want to be either haha

[sciencoking]

1:15 if you listen you hear some people outside shout something xD

[benpetben]

wig man ITS fake!!!

[maekern]

I wish that "proper" science journalism was as good as what you guys are producing, even though you are scientists rather than journalists. Or perhaps your videos are such good science journalism BECAUSE you are scientists rather than journalists.

[groo1111]

And for those of you who might wonder what exactly dying to a black hole would mean, look up spaghettification (correct my spelling please) yeah it would suck, alot. lol.

[groo1111]

I know harvester, we get bombarded by cosmic rays. I'm just joking really, but I'd rather die to a black hole than a nuclear bomb any day. What a way to go :D

[gameking438]

hahaha typical stereotyped look of a scientist hahaha

[periodicvideos]

Spanish subtitles now available on this film

[periodicvideos]

Hi thanks for watching our films... for some the clips and mistakes you weren't supposed to see, have a look at our first outtakes video at our behind-the-scenes channel, nottinghamscience

[mcynthi16]

ah....this hair...i love him xD LOL

[groo1111]

well to all you that thought 2012 was the end, it seems that this micro black hole can take 50 months to 50 years, which puts it at 2012 if you go the months route. We're dead, lol.

[harvesterofhope420]

huge particles collide at even higher force right outside our atmosphere all the time, creating larger amounts of energy than we could ever manufacture. dont fear black holes, fear bush, an d mcain obama.

[lanceawatt]

I bet a friend £50 that the earth WON'T end in 2012. If it doesn't, ill be 50 pounds richer, if it does, well, I won't have to pay him anyway, because our carcasses will be in some next dimension.

It's a win win situation!

[HiAdrian]

Yup, that thought crossed my mind as well. But most people can't be conned that easily :[

[ShipmasterFlint]

Hey mr scientist, you do realize what happens when Matter and Anti-Matter come in contact right?

[Zopswe]

OMFG xD

[87lancerguy]

I dont think we need to be messin with nature and physics to the point of needing to build a large hadron collider. They dont even know whats gonna happen when they REALLY use it. For all they know they could create enough anti-matter to start a black hole...smart

[netsight]

Supa-cool scientist, think he uses helium shampoo! haha

[lamiomama]

oh my lord¡too many hair O.O

[obrijanavolina]

what is it with scientists and mad hair?

[HiAdrian]

they'll eventually find a gene responsible for both.

[Flighn]

I bet he studied afro physics at Uni.

[unInnocentBystander]

Haha Flighn

He minored in hairsray chemistry too.

[womba89]

wrong button, I was suppose to vote thumbs up:P

genius comment:P

[hk86]

he definitely looks like a scientist

[slowbaru]

who is this king of gods

[demonic7agony]

i didn't like the idea that lhc will startup 2008 bec. i had a strong feeling its the cause of 2012 consciousness shift. ^ maybe it'll be delayed till mid 2011.

[87lancerguy]

I don't think they need to start it up period. Theres some things humans just were not meant to do...like create anti-matter. WHAT ARE WE GONNA DO WITH IT???

[zukodama666]

DUDE I WANT HIS HAIR

[Roque07]

me too, but i have a small house..

[kevkittils]

when a superconducting magnet loses this it's called a quench and is very impressive for another reason besides the fact that it can melt the coils. And that is the pressure that builds up as a result helium going from a gas to a liquid. One liter of liquid helium equal over 700 liters of helium gas, so I'm sure that there will be some not so happy technicians changing some gaskets.

[alanna4858]

so interesting. needless to say i missed the magnet lessons and helium lessons at school. thanks for making this guys! make loads! loads more

[ProctoLogic]

love the hair

[Clinkzzzy]

i want same hair cut plz!!!<3:D

[R03l4nd]

HE IS CUTE :D

[burnzyovslaty]

omg hes a specky big wig

[system0system]

is that hair a joke OMG THATS INSANE

[Shademp]

It is compulsory for great scientists to have weird hair. Believe me, I've seen it everywhere.

[Wirefrost]

ohhhh I want to boil in the top of the mountain too ... :D

[Wirefrost]

I WANT THE SAME HAIRCUT!!!!!!!!!!!!!!!! shampoo my hair with helium and protons and practicles and stuff!!!!!!!! and finaly I want to dance in the center of the colider nude with this haircut and sing "huuuge circles round and round lalalaa lalaa la la round and round lalala la" :D :D :D

[Tigris1989]

He forgot to mention that the material between the coils is also a VERY important for the magnetic power ...

a finger for example is crap, air is crap, but a metal is VERY well for extra magnetic power...

(Unless it doesn't affect the electric field but the 'induxie' or something... ugh, it's been a while since i learned that in school :\ )

[lhiasczkter]

Hooo Yeah awesome hair cut, I want the same !!!!!

[modymoda1144643]

but i like this

[modymoda1144643]

Why his hair like this

all them like this??

[dreamweaver60]

i liketo see more!

[Rebeccaaaaaaa]

I love his hair, it looks like a cozy pillow. I think his role model was Einstein :)

HEY, I just understood a thing: it's all in the hair! Smart people have big hair.

[IncoherentRussian]

In short, helium is used to cool the magnets in the hadron collider. The helium escaped, nothing was cooling the magnet. So it heated up, the wires gained resistance, and the magnet melted.

[phyerdragon76]

a scientific Phil Spector...

[periodicvideos]

Hi, for those who enjoy our videos, we have posted a funny video of outtakes and mistakes at our behind-the-scenes sister channel, "nottinghamscience"

[saintsosha]

notice the text on the two screens in the background swithcing between them.... that's what this vid is really about

[gasmarkfive]

The text on the background computers! Awesome, how do they do that?

[ShawnGlory]

twin screen mode

[sjoerdsuper]

you reminds me on Dr. Kleiner xD

[shield543]

ROFL, sjoerdsuper...he is more like a poodle that has recently seen a hair dryer, not Dr Kleiner, lol...

[SSaTTaNA]

ahaha what'a face and hair so funny:))0

[derbo411]

Did somebody say.. stereotype?

[qatarfaisal]

hahahahaha nice hair

[Gademanyak]

Afro scientist ;D

[winxniw]

Nothing compared to Phil Spector. You should see that fro.

[Brian1454]

OMFG that hair!

HAHAHAHAHAHAHAHAHAHAHHAAHHAAHA­HHAHAAH

XD XD XD

[raiden233]

thanks:D i appreciate what u taught me

[Uatarreu]

omg a poodle

[HighHeelzMusic]

is this albert einstein ? : )

greetings high-heelz, look too our videos please...

[thugboy10b]

nice fro bro!

[LUFTRITTER01]

Very interesting!

Excellent!

[xCallmekawaii]

ROFL YOUR HAIR LOL

[hafizfelix2000]

hahahahhaa

[ZDS373HR]

Hahahahahaha! White afro! ;O

[hafizfelix2000]

hahahahaha

[UnknownErrorMD]

I bed you've chosen that phisician due to his hairstyle :)

[djnagureo]

He's a physicist not a physician.

[periodicvideos]

Actually, after all that, he is a professor of chemistry.

[jaytechnical]

he's a comedian

[RoadRunnerLaser]

Ah... Not an afrophysicist then.. ;)

[lanceawatt]

lol joker!!

[waragainstgreed]

i think he actually means profession.

[UnknownErrorMD]

english is not my first language, i beg your pardon sir.

[kurtilein3]

okay, you are right.

a half-life of only 22 minutes and the fact that its so unstable that only 20 grams of it exist at any given moment on our planet... well, it could be artificially created.

but the element with the second highest electronegativity would be caesium, and weve already seen that. (francium is the highest).

two options left: they simply used more caesium, or they faked it, using something like a chemical explosive, or at least additional chemicals. there is no other option.

[hockeycrazed999]

lol....is your hair like that on purpose? it looks kinda like a nest.

[Rovelius]

It's cool how I understood everything he said. Keep'em coming, I like those vids.

[Slo888]

NICE FRO!

[jessicabittar]

Thanks for this video!!

LHC is really 'famous' nowadays, it's important that we know everything about it.

Congrats, Professor Poliakoff!

[revengerste]

what a hairdo were you the drummer from slade?

[nosotroscuatro]

Keep them coming. I love these videos. I watch them all.

[Maghuma]

I really love these videos. I've watched them all and am currently rewatching them. I study chemistry and these videos are a great way to relax during my 'study-breaks' without ever stop learning.

[anderzofsweden]

Nice hair! xD HAHAHA

[librano]

he makes me wish i wasnt bald =)) subscribed!

[Fardorfar]

Is this the Back to the Future 4 trailer?Where is Marty?

[6manchesterutd6]

How cool. Itd be awesome if u guys also explain how exactly do magnets make the particles spin in circle.

[deepakm]

nice upload!

[SauronsEye]

Someone put a red nose on him and send him to the circus.

[mddod]

your guys better then school!

i love chemistry

big fun

[huntermccartyney]

Excellent video as always. I love these.

[archaedemos]

you guys rock thnks for the upload!!!!!!!!!!!!!

[Kalyvakos]

This explanation was just brilliant. Very informing. Thank you so much!

[surrealistgeek]

Cogent explanation - thank you.

It had never occurred to me to wonder why He has such a low boiling point, but it makes sense now. My immediate thought from that is, where does H fit in? Memory tells me it sublimes, and logic tells me its interactions will be stronger than a noble gas like He.

*checks*

Nope, memory's wrong - hydrogen is a liquid between 14.01K and 20.28K. Thanks for prompting me to learn something, and in a way that I'm likely to remember.

[armskoteic]

informative and easy to understand for the common public out there. Great job!

[vaarsuviusprime]

Awesome vid as always. It is really interesting information.

[figure1337]

periodicvideos is one of the best video producers on youtube. Thanks for all the info.

[joseph2442]

Thank you for making these videos, they make me remember the reason that I'm studying A Level chemistry because of all the peculiarity involved in chemistry. Thanks.

[TeamVacaville]

love these things! Keep it up! I especially love that you use current events to drive the topics sometimes!

[kurtilein3]

i guess the next video will be about francium...

[DuskY1991]

Omg, that was exactly what I was thinking, and then I saw this comment. Although I found it unlikely I still thought it :D

[windowlicker1]

hah awesome. you guys are awesome thanks for all the great videos.

[deepakm]

yay new video!!

[JasoniumGH]

lol centigrade?

[MasterFlanJ]

What reaction was taking place in that clip?

Have you been messing around with Caesium again?

You Nottingham proffesors are very rebelious.

Well done for watching this film to the end... I won't ruin the surprise by telling you what caused that reaction, but it was not caesium!!!
